Hi,

Ok, so I pulled off one of the spark plugs today off my 77 transmode. It looked in decent shape, I cleaned it. The gap was huge...not sure how large since I didn't have a large enough gauge to measure it with.

Bought the RV back in July and not sure when the plugs were replaced but I did notice the acceleration (when I drove the RV home) was bad.

Is the bad acceleration caused by the large spark plug gaps ?

Should I re gap the plugs to .040 ?

And would replacing the plugs improve the gas mileage by any noticeable amount ?

Should I stick with the AC Delco plugs or are the plugs made by Bosch, NGK, Autolite, Or Nipendenso a better choice (performance and gas mileage wise) ?

Thank you for the help.
AJ
